1. Move the modem. The line connecting the modem to the phone outlet can easily be 20 or 30 feet.
2. Move the laptop (works very well as you noticed).
3. Go wired.
4. Buy a repeater.
I have a spot in my home where my download speeds are significantly lower than what I'm signed for with my provider. Unfortunately, this spot is where I use my laptop most often. There is a TV and Blu ray player in this room also. I have had 2 ATT service techs visit and neither could come up with a solution. The modem is in a lower level room (basement office). The interesting thing is that if I take just 3 steps into another room, the download speed jumps from 3-5 mgps to 16-20 mgps. The ping and wifi reception are both very good, as measured by the techs. Can anyone out there offer a solution? Thanks.
